Helically Loaded Magnetic Loop Antenna
Helically Loaded Magnetic Loop Antenna From Author and Designer Rich K8NDS This magnetic loop antenna is about 50% smaller in diameter then a text book magnetic loop. The performance is outstanding, it compares or is better then a 1/2 wave dipole mounted 1/2 wave above ground. It is also directional, when turned with a rotor it quite often changes around 10 to 12 db from the plane of the loop to broadsideI think you will be quite surprised at the functionality of these small antennas.
